May 9, 2008 · The KKM barrel is button rifled, and the others are broach cut. No need to scrub your barrel when cleaning, this will actually do more harm than good. Just a wet patch, then a dry one if you really want to but rearely neccessary when not shooting lead. You made a good choice, KKM makes a nice barrel.

Jan 7, 2025 · The Glock 20 in any generation, just like ALL 10mm pistols old and new, was created to handle ammo rated from 520-650 ft/lbs. These frame blow outs and “explosions” are happening because the uneducated are putting aftermarket barrels like KKM with tighter tolerances into their guns and firing extremely overpressured cartridges out of them.

Jan 18, 2024 · I have a few KKM threaded barrels for various Glocks and clones, including a G22.3, G40.4 and another used in a G20.3 and a LoneWolf Timerwolf in 10mm. They seem more accurate than OEM, but it's probably my subconscious rationalizing their cost. I would recommend them but can't say with any certainty they're more or less accurate than OEM.

Nov 10, 2011 · A stock Glock pistol will have a better chance having a KB! than my KKM barreled pistol failing to function properly. I don't work for or have any professional relationship with KKM or any other aftermarket mfgrs. I am a customer and I know my pistols. I carry KKM and full power 10mm loads. (135nos@1700fps avg. chronographed; 866FPE).

Oct 21, 2024 · And I have a KKM barrel on order. Hopefully some combination of these additional parts gets me to a functional pistol. All this to say: I'm extremely disappointed that the Glock 20 Gen 5 fails to do what a 10mm pistol needs to be able to do, even after trying a bunch of different aftermarket parts to get it to work (none of which should be ...

Jan 13, 2018 · I ultimately sold my KKM barrel as it never made it out of the bag. Anyone who tells you there is a single deleterious effect from shooting 40's from your G29/G20 guns, is talking from flawed theory, versus actual fact. But if it makes you feel better, the KKM conversion barrel should work without a hitch. PS - 40 from a G29/G20 is absolutely ...

Mar 20, 2020 · I think with careful work up, the KKM barrel would handle slightly heavier charges of AA9 and might get close to 900 ft-lbs ME. However, I began working on .45 SUPER for a G21 using an ES350 muzzle brake and easily got 1345 fps MV with a 230gr bullet for 924 ft-lbs ME. IMO, a KKM 6" 10mm barrel w/ muzzle brake should also easily exceed 900 ft ...

Apr 10, 2004 · i have a kkm for my g22 in .357 its a lot more accurate then the g31 i have if i shoot them off of sand bags. i noticed that the kkm barrel seems to be heavier then the glock factory barrel less muzzle flip. the kkm looks to have a quality finish and seems to lock up tighter then the factory barrel.

May 4, 2019 · G19 G3, RMR + KKM Barrel/Comp issues Never had any issues until today. Even with powder puff reloads. HST cycles perfectly. 115gr CCI brass, Federal Brass - failure to feed and occasional stove pipe. First round fires and ejects fine. Second round stoppage, bullet is tip up, slide is halfway...

Jan 8, 2012 · I'm curious about aftermarket G20 barrels with better case support, always looking to be safe and shovel more into this moneypit of a hobby :cool:. The IGB seems interesting, though pricey, advertising drop-in fit and "fully supported" chambers. My interest is more in minimizing bulging brass...
